go: update to go 1.9

* Rebased patches
   - dropped armhf-elf patch, should no longer be needed
   - dropped syslog patch which should not have been imported to begin with
   - reworked other patches as needed for the updated code base

* Updated native, cross, cross-canadian .inc files to
  remove some testdata directories that contain .a files
  that strip chokes on during sysroot staging

+Subject: [PATCH 5/7] cmd/go: make GOROOT precious by default
+
+For OE builds, we never want packages that have
+already been installed into the build root to be
+modified, so prevent the go build tool from checking
+if they should be rebuilt.
+
+Also add an environment variable to override this
+behavior, just for building the Go runtime.
+
+Upstream-Status: Pending
